Yanny or Laurel

This auditory trick was apparently popular two years ago, but it wasn't until a recent episode of Last Man Standing did we hear of the "Yanny" or "Laurel" debate.  In the recording available at this New York Times link, about half of us, including me, hear "Laurel" while the other half, including my wife, hear "Yanny".  This recording is interactive, so you can change the mix of frequencies, high to low, which changes the pronunciation just enough to hear the other word.
